The first year my great Aunt Rose moved to florida and we had to do Pesach for the entire family without her, she gave us the recipe for the chopped liver knishes but left out a key ingredient – if you don’t add matzah meal to the potatoes they’re sticky, and won’t form knishes. So, we spent hours pealing potatoes off each other’s hands trying to make the knishes. when we called aunt rose to tell her it didn’t work she said: “of course! you didn’t use enough matzoh meal!” my mom said: “enough?! we didn’t use any!”
